Detailed Description

The following provides a more detailed description of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 4, the vertical plate 1 of the present invention comprises a vertical plate 1, a connecting pipe 2 is provided on the right side of the vertical plate 1, one end of the connecting pipe 2 is connected with a long pipe 3, the long pipe 3 is arranged along the horizontal direction, the left end of the long pipe 3 penetrates through the vertical plate 1, the long pipe 3 can rotate on the vertical plate 1 but cannot move left and right; two through holes which are arranged along the horizontal direction are arranged on the vertical plate 1, the distance between the two through holes and the center of the long pipe 3 is equal, and air inlet pipes 4 which are in one-to-one correspondence with the through holes are fixed at the rear end of the vertical plate 1; the upper end of the connecting pipe 2 is provided with a short pipe 5 parallel to the lower side pipe, the left end of the short pipe 5 is sleeved with a movable cylinder 6, the movable cylinder 6 can move left and right along the short pipe 5, the right end of the short pipe 5 is provided with an annular bulge, a pressure spring is connected between the annular bulge and the short pipe 5, the left end of the short pipe 5 is fixed with an annular block 7, and the annular block 7 is matched with the through hole.

In order to better connect various pipelines with the long pipe 3 and the air inlet pipe 4, the air inlet pipe 4 and the outer side of the left end of the long pipe 3 are provided with a circular ring with a wedge-shaped structure.

In order to realize that the long pipe 3 can rotate on the vertical plate 1 but can not move left and right, the long pipe 3 is sleeved with the cylinder 8, the cylinder 8 is fixed on the vertical plate 1, and the cylinder 8 is connected with the long pipe 3 through a bearing.

In order to realize the switching between the two air sources, the left end of the annular block 7 is a spherical surface, the right end of the through hole is provided with a chamfer, and when the annular block 7 corresponds to one of the through holes, the left end of the annular block 7 can press the through hole under the action of the pressure spring.

In order to ensure the sealing effect, a sealing ring is arranged on the spherical surface of the left end face of the annular block 7; a sealing ring is arranged between the movable cylinder 6 and the short cylinder.

For the sake of beauty and convenience for the switching operation of screwing by hands, the vertical plate 1 is in a triangle shape, the long tube is positioned at the lower half part of the vertical plate 1, the two through holes are positioned at the upper half part of the vertical plate 1, and the long tube 3 and the two through holes are distributed in an inverted triangle shape.

It should be noted that the device is suitable for seamless switching between different gas sources, such as switching between a ventilator and an oxygen cylinder, or switching between two ventilators, or a replacement link between two oxygen cylinders, in short, for switching the gas source used by a patient.

For convenience of illustration, the present application takes transporting patients as an example for illustration. When transporting a critically ill patient, the pipeline on the breathing machine needs to be switched into the pipeline of the oxygen cylinder. Initially, the left end of long tube 3 links to each other with patient's respiratory mask, it links to each other with the breathing machine to be in left intake pipe 4, as shown in fig. 1, 2, when transporting the patient, at first go up the venthole with the intake pipe 4 that is in the right side with the oxygen cylinder and be linked together, at this moment, hold riser 1 tightly on one hand, another hand rotates connecting pipe 2, make connecting pipe 2 rotate round long tube 3, because 7 left ends of annular piece are the sphere, so annular piece 7 contracts right and swings along with connecting pipe 2, until reaching the through-hole department on right side, annular piece 7 compresses tightly to the through-hole under the effect of pressure spring this moment, pull out the pipeline on the breathing machine, the air supply switching completion this moment.

In this scheme, left intake pipe 4 links to each other with the breathing machine, and 4 oxygen cylinders in the intake pipe on right side are connected, and both are different air supplies, then rotary connecting pipe 2 is rotated from left to right, as long as annular piece 7 corresponds with right side intake pipe 4, then supply with, the dependable performance just can be guaranteed to patient's required oxygen.

In this scheme, the pressure spring on the activity section of thick bamboo 6 can keep the annular piece 7 constantly to compress tightly backward, in the transportation, can help medical staff rotatory fast connecting pipe 2, guarantees to accomplish the switching of air supply in the utmost point short time.

In this scheme, a long section of thick bamboo is the article font of invering with two control keys of all standing for in air supply conversion process, the switching of air supply need not too big can be accomplished to the turned angle of connecting pipe 2, further guarantees to switch efficiency, is favorable to the disease to transport efficiency.

Riser 1 in this scheme is the equilateral triangle of inversion, and three angle all makes and be the fillet, prevents to cut the hand condition in nervous transportation.

The utility model discloses the structure is ingenious, and switching oxygen source that can be convenient can be at the fast switch over between two oxygen sources of difference, reduces interim oxygen deficiency time, makes the patient hardly notice the oxygen deficiency, and easy to assemble and regulation, and the joint is convenient, reliable, does benefit to the transport efficiency who accelerates the disease.
